85%Weight 40%Scale 1-3Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a well-structured, actionable decision framework with a clear sequenced workflow and a properly disclosed one-level-deep reference bundle. Its main weakness is conciseness: dense enumerations and some cross-sectional repetition make it longer than the lean ideal.
Suggestions
Tighten the long enumerations in "Identify the highest-risk failures" and "Make rendering deterministic before asserting" by grouping related bullets and trimming near-duplicates, since the layered-testing philosophy is already restated in Coverage Heuristics and Output Expectations.
Consolidate the repeated unit/component/visual/E2E layer guidance so it appears authoritatively once (e.g. in Coverage Heuristics) and is referenced elsewhere, reducing cross-sectional repetition.
Verify the ../../references/foundations, ../../assets/templates, and adjacent-skill SKILL.md paths resolve in the deployed bundle, or move them behind the local ./references/ group so all surfaced links are reachable from the skill root.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body avoids concept-padding Claude already knows, but at ~145 lines with multiple 20+ item bullet lists (e.g. the "highest-risk failures" and "Make rendering deterministic" enumerations) and restated layered-testing philosophy across Working Pattern, Coverage Heuristics, and Output Expectations, it could be tightened despite being accurate. | 2 / 3 |
Actionability | For an instruction-only strategy skill the guidance is concrete and specific — "unit tests for pure data shaping and formatting logic", "fixed viewport and container size", "reduced or disabled animation", "mocked network responses" — and points to executable templates like the playwright visual-regression starter, satisfying actionable guidance without requiring inline code. | 3 / 3 |
Workflow Clarity | The Working Pattern is a clearly sequenced six-step process (identify risks → choose layer → make deterministic → mock at boundary → define non-goals → include degraded modes) with explicit checkpoints such as "explicit render-ready signals before capture" and supporting checklists in Coverage Heuristics and Output Expectations. | 3 / 3 |
Progressive Disclosure | The overview points to a well-organized References section whose local ./references/ files (test-level-selection, unit-and-component-tests, visual-regression-and-image-testing, data-mocking-and-fixtures, e2e-dashboard-and-export-strategies, avoiding-brittle-over-testing) are real, one level deep, and clearly signaled into themed groups. | 3 / 3 |
